Hello,

There are a few suggestions about the DNS over HTTP draft made off-list,
which I will try to characterize here:

* We should expand the motivations to explain why DNS over HTTP makes
  sense at all. 

* We should restrict the protocol to TLS.

I am happy to expand the motivation section, although I am beginning to
wonder if it will ever be enough. :)

As for a requirement for TLS... the document currently says that
implementers SHOULD use TLS. My own feeling is that this should be
enough; apparently the recommendation to require TLS was made in the
HTTP/2 working group and rejected, so I am not sure that we need to
re-visit the entire discussion around the DNS over HTTP protocol.

https://http2.github.io/faq/#does-http2-require-encryption

Note that I do not have a strong preference here. This is a working
group document, so if there is consensus for requiring TLS then that's
how it is.


A final oversight that occurred to me is that there should be a privacy
section. This is because since the DNS over HTTP serves as a DNS
resolver that all of the privacy considerations of a normal DNS
resolver apply, and should be mentioned (probably referencing RFC 7626).

Cheers,
